Mattress was the term applied to ground-based British-devised multiple rocket launchers during World War II. Compared with the German and Soviet counterparts (the Nebelwerfer and Katyusha launchers respectively), the western Allies deployed these weapons late in the war. Nevertheless, they did see useful service as artillery support during the crossings of the Rhine and the Scheldt rivers.
